Examples of air pollution is one of the problems to be solved inthe SDGs. Most of the substances that cause air pollution are emitted activities behaved by our human family. Let’s think about the causes of air pollution, its impact on humans and the environment, and countermeasures possible to be taken against those impacts.
The Sustainable Development Goals (SDGs) have been set out to solve global issues. Various efforts are being made around the world to realize them. In this context, examples of air pollution is considered to be a major barrier to achieving the SDGs. The seriousness of the examples of air pollution problem can be seen from the fact that is mentioned in the following four development goals.
Goal 3: Health and Welfare for All
Goal 7: “Clean energy for all”.
Goal 11: Create communities where people can continue to live.
Goal 13: Take concrete measures to combat climate change.
In order to realize these goals, examples of air pollution is an inseparable part of the problem.
In this article, we will explain why examples of air pollution occurs, the problems and health hazards caused by examples of air pollution, and Japan’s air pollution countermeasures.
What are the causes of examples of air pollution?
The atmosphere means the air surrounding the earth. The air is polluted by chemical substances contained in automobile exhaust and factory smoke. Gases and particulate chemicals not only pollute the atmosphere, but also turn into harmful substances in the air that have adverse effects on humans, animals and plants.
Unfortunately, most of the pollutants that cause examples of air pollution are generated by our human lives. In addition, it is important to remember that they can also come from natural disasters such as forest fires and volcanic eruptions.
Problems and health hazards caused by examples of air pollution
What are some of the problems caused by examples of air pollution? The health hazards caused by examples of air pollution will also be explained.
Pollutants in automobile exhaust and factory smoke are transformed into toxic substances called photochemical oxidants when they are exposed to strong sunlight. When these toxic substances accumulate in the atmosphere, they create a white blur. This is what is called photochemical smog.
When photochemical smog occurs, it can cause health problems such as flickering eyes and sore throats. It is also said to have adverse effects not only on humans but also on plants.
We have been hearing more and more about PM2.5 over the past few years, and its name comes from the fact that it is a fine-grained pollutant of less than 2.5 micrometers. Because the particles are so small as to be invisible, they can penetrate deep into the lungs and adversely affect our health.
It is said that it can cause asthma, bronchitis, and pneumonia, so the elderly, children, and people with respiratory or circulatory diseases should be especially careful.
Yellow sand from the deserts of inland East Asia, such as China and Mongolia, is called “yellow sand” when it is blown in by westerly winds. Yellow sand rolls up high in strong winds, spreads in the atmosphere, and rains down on Japan, and the amount is increasing every year.
One of the reasons for the increase of yellow sand is the progress of land development in China. As a result of the continuous development of land by clearing forests, China has been experiencing an increase in desert-like dry land.
Yellow sand contains harmful chemicals that cause allergies, respiratory diseases, and damage to crops, making it a major social problem.
Acid rain means the rain with a high degree of acidity. Sulfur dioxide and nitrogen oxides from automobile exhaust and factory smoke are converted into sulfuric acid and nitric acid in the atmosphere. These substances are highly acidic and dissolve in rainwater, causing it to fall as acid rain.
Acid rain can kill forests and plants, and dissolve the surface of buildings such as concrete. The often discolored color of buildings and statues can be attributed to the effects of acid rain. It also causes damage to living things in the water, such as the death of fish in rivers and oceans.
examples of air pollution Control in Japan
In order to reduce examples of air pollution, Japan is promoting the use of electric vehicles and a shift to sustainable energy. Electric vehicles use the power of a motor stored in a battery, and thus can run without emitting harmful exhaust gases.
In addition, instead of producing energy from limited resources such as coal and natural gas, we can use sustainable energy sources such as solar, hydro, and wind power, thereby avoiding the emission of harmful substances produced when fossil fuels are burned.
In addition, Japan has the examples of air pollution Control Law, which stipulates emission standars for pollutants from factories and workplaces according to the type of substance and the type and scale of the facility. This ensures that environmental standards for pollutants are kept below a certain level.
For a city with clean air and healthy living
Countries around the world are also taking measures to combat examples of air pollution, and improvements are gradually being made. However, in order to create a city where all people can continue to live in good health, we need to change our individual awareness and behavior.
This examples of air pollution problem is the result of our over-consumption and convenience-seeking activities.
There are many things that we can do in our daily lives, such as avoiding unnecessary use of electricity and reducing car travel as much as possible. Avoiding over-buying and reducing waste will also help reduce air pollutants.
Why don’t you take this opportunity to learn about examples of air pollution and think about what you can do to help?
